Question

Chad hopes to save more than $450 dollars this year. He expects to be able to save $9 each week. There are 52 weeks in a year, so Chad thinks he will be able to save $468 in one year. Is Chad's answer reasonable? Use rounding to make an estimate and tell whether $468 could be a correct result. Explain your answer.

Answer 1

Answer: yes

Explanation:

If you round, then $9 will round up to $10 and 52 will round down to 50. Then, you multiply 10 and 50, which equals 500, so it is a reasonable guess.
